Abstract

The utility model provides a leather bag. When the leather bag is not used, the leather bag can be folded to be compact. When the leather bag is used, the style of the leather bag can be recovered to keep the style. The leather bag has light integral weight and convenient use. Piece-sheet-shaped leather material and leather lining material can be used for forming a front part, a back part, two side parts and a bottom-surface part. A frame body surrounding a circumference is sewn into a periphery between the leather material and the leather lining material along the front part and the back part. A synthetic-resin gasket is assembled between the leather material and the leather lining material of the bottom-surface part. The material of the frame body is made of the super elastic alloy of an Af transformation point of which the temperature is lower than the temperature when the leather bag is used. Under the use temperature of the leather bag, the leather bag is deformed by being imposed with a deforming force. When the deforming force is removed, the front part and the back part can be recovered.

Description

Suitcase

The utility model relates to a kind of and the leather handbag higher suitcase of specific rigidity mutually.

As shown in Figure 5, on the higher suitcase of the rigidity with face portion a, the b of back side portion, the facial c in both sides and bottom surface sections d, be the maintenance pattern, for face portion a, the b of back side portion and bottom surface sections d, constitute between the leather substance of those parts or constitute the leather substance of those parts and underedge between be fitted with the sheet that each face almost is paved with and open the shape liner.

This suitcase is owing to keep the weight relationships of pattern with liner, thereby suitcase integral body is heavier, simultaneously because the time spent will not keep pattern, therefore same large volume state when the carrying of user mode not and keeping occasion also will be kept and use yet.

The problems referred to above that the utility model exists in view of prior art, its purpose be to provide a kind of can be when not using by collapsed compactization, then recover pattern during use and keep pattern and overall weight is light, the user makes suitcase.

For realizing above purpose, the utility model suitcase comprises: face portion, back side portion, both sides face and bottom surface sections, its face portion and back portion do not have the framework of the superelastic alloy system of shape memory, the facial linerless in face portion, back side portion and both sides keeps the pattern of face portion and back side portion by above-mentioned each framework.

Framework is (more no matter large or small than suitcase by having.Comprising the little suitcase that uses as wallet) superelastic alloy of the Af transformation temperature that temperature when using is low constitutes, and (for example 10-30 ℃ of the temperature when suitcase uses, it better is 0-35 ℃,-5-40 ℃ is then better) under be out of shape by applying the stress-induced phase transformation that deformation force produces from austenite to martensitic phase, then return to the corresponding shape of pattern with face portion and back side portion by removing this deformation force.

The means that framework is installed in face portion and back side portion can be sewn between the leather or leather and cloth between, also can take to carry out any means such as bonding with bonding agent.

The pattern that keeps face portion and the back side portion during use owing to the framework of superelastic alloy system, and since at face portion, back side portion and both sides face without liner, so can alleviate the suitcase overall weight.

When not using by with the facial folding plastic deformation that makes framework produce the appearance aspect of face portion, back side portion and both sides, thereby can realize densification.

As removing the required load of unfolding face portion and back side portion, then framework is got back to original shape and is recovered face portion and the pattern of the back side portion during use.

When bottom surface sections has liner,, can prevent that also bottom surface sections is sagging even institute's article of putting are heavier in the bag.

Under the situation that framework only is provided with along the peripheral part of face portion and back side portion respectively, can further alleviate the suitcase overall weight.

When framework not only is separately positioned on the peripheral part of face portion and back side portion, but also when setting within it side, can more effectively keep and restore the pattern of face portion and back side portion.

Below in conjunction with description of drawings embodiment of the present utility model.

Simple declaration to accompanying drawing:

Fig. 1-Fig. 3 is the stereogram under the utility model one embodiment different conditions.

Fig. 4 is the stereogram of another embodiment of the utility model.

Fig. 5 is the stereogram of prior art suitcase.

Fig. 1 to Fig. 3 is the ideograph as the utility model one embodiment leather handbag, and wherein Fig. 1 is the stereogram of expression user mode, and Fig. 2 is the stereogram of eighty percent discount state, and Fig. 3 is the stereogram of three folding states.

This handbag by square face portion 10, back side portion 12 and bottom surface sections 14, leg-of-mutton both sides face 16 and be sewn on face portion 10 respectively and back side portion 12 on mobile division 18 form, its structure is for opening and closing the middle opening of face portion 10 and the rising wood of back side portion 12.Face portion 10, back side portion 12, both sides facial 16 and bottom surface sections 14 are sewed with sheet and open shape leather shell material and leather sheet material (diagram is omitted).

Between the leather shell material of face portion 10 and back side portion 12 and leather sheet material, sew up framework 20 around whole periphery along its peripheral part.Between the leather shell material of bottom surface sections 14 and leather sheet material, then be fitted with plastic liner 22.In addition, framework 20 also can be located at peripheral part and diagonal part thereof as shown in Figure 4.

The superelastic alloy of the Af transformation temperature that the temperature when framework 20 is used than suitcase for having is low is made.Spendable superelastic alloy such as NiTi alloy, CuZnAl alloy etc. there is no particular restriction.Be out of shape by applying deformation force generation stress-induced phase transformation under the temperature of this framework 20 when suitcase uses, and reset into the square of face portion 10 and back side portion 12 patterns by removing this deformation force.

Owing to without liner, and only framework 20 is set at face portion 10, back side portion 12 and both sides face 16, so the suitcase overall weight greatly alleviates at the peripheral part along face portion 10 and back side portion 12 respectively.

Framework 20 owing to superelastic alloy system during use keeps face portion 10 and back side portion 12 for square.In addition, because bottom surface sections 14 has liner,, can prevent that also bottom surface sections 14 is sagging even institute's article of putting are heavier in the bag.

When not using by with face portion 10, back side portion 12 and both sides facial 16 as Fig. 2 or the folding plastic deformation that makes framework 20 generation appearance aspects of shape shown in Figure 3, thereby can realize densification.

As removing unfolding face portion 10 and back side portion 12 required loads, then framework 20 is got back to original shape during use, and face portion 10 and back side portion 12 restore as shown in Figure 1 for square simultaneously.Under situation embodiment illustrated in fig. 4, the pattern of face portion 10 and back side portion 12 can more effectively keep and restore.
